Thank you for your replies! Yes, I'm staying away from every doubler scheme and any ponzi too. I was thinking about hashnet though seems like a good idea. I checked out bitfury as well, their machine is quite nice I'd say better than bitmaintech's s7. It may be helpful to my friend who was talking aout buying s7 and just lost 1 BTC in satoshidice.com. I told him not to risk it but why'd he listen? So, I know now that I need to stay away from gambling sites as well.

Hi,
I'm quite new here, in fact this is my first post. I am a college student and I saved around 60,000 INR and bought 2 BTC in December last year. I'm looking forward to invest them since I've lost around 0.5 BTC investing in BTCJAM. I don't think I can trust that website. Moreover even A rated users have opted for refinance loans. I agree this could be due to fluctuating BTC price but for people like me it's really difficult to recover such a loss.
Thanks in advance to all those who're going to give me good advises.
